47-54 Chevrolet Pickup Bolt-In Crossmember Product Description:

Using the front end geometry the Ford engineers applied to the Mustang II, a crossmember was developed to enable street rodders everywhere to enjoy a modern front suspension. That is why there are no changes in critical front end geometry that can lead to hazards like bump steer.  Mustang II kits fit the frames hazards easily and yield a 3-4 inch suspension drop.
